Manual entry of power after a workout that only synced heart rate

When I work out in a gym, I cannot get the power to sync, so I only get my heart rate data from my Garmin watch. But I can see the Watts I put out during the ride. I would like a feature that asked me what percentage of the ride I was within the specified power zones during the workout. Then I just input a percentage like 95% of the time. Then the AI can take that into account.

Additionally, I notice when I do a V02 Max session, often the power I am to maintain does not result in a very hear V02 Max exercise. Yet even though I enter a lower RPE score, it does not really adjust the power for the next V02 Max. So maybe add a quick check for people to say whether they felt they actually got a V02 Max out of the session and then adjust accordingly.
